How to Change Tkinter Button State?
Tkinter is a Python Package for creating GUI applications. Python has a lot of GUI frameworks, but Tkinter is the only framework that’s built into the Python standard library. Tkinter has several strengths; it’s cross-platform, so the same code works on Windows, macOS, and Linux. Tkinter is lightweight and relatively painless to use compared to other frameworks.
In this article, we are going to learn how we can change the state of a Button.

Let’s understand this with step-wise:
Step 1: First we are going to import the Tkinter module and some widgets that we need.
If you are using Python2 then change tkinter to Tkinter and also tkinter.ttk will not also work so import widgets from Tkinter itself.
Step 2: Now we are going to create an App class that will contain all the Buttons and Labels.
Step 3: As you can see in the above code, we have a function attached with Button2 i.e changeState function next we are going to implement this function. In this function, we will change the State of Button1.
Step 4: In this step, we will create the main function that will run this application. In the main function, we will set the application title and geometry and instantiate our App class.
Below is the full implementation:
